U3

The U3 line has 15 stations and is 11.9 km long. The line has roots that stretch back to 1913, although the current station lineup was created in 2004. Heidelberger Platz station is my vote for most beautiful station in Berlin. It’s magnificent. It’s not just the platform that is grandiose, also the stairs and entrance passages. In fact, the entire line from Hohenzollernplatz to Breinbachplatz deserves an honorable mention.
